Nice experiment. Thank you for sharing. I'm looking into Pictorialism right now and how to create this style.
I got me a new Wollaston Meniscus lens recently from Reinhold to make some ULF tests for contact printing.
The Wollensak Verito diffused focus lens and your lens are often mentioned in discussions and it is nice to see how you did this.
I recently saw a post (but where?) demonstrating taking this lens apart and adjusting it - probably the same way you did?
